- * @brief Multiplies a Q7 vector by a scalar.

- * @param[in]       *pSrc points to the input vector

- * @param[in]       scaleFract fractional portion of the scale value

- * @param[in]       shift number of bits to shift the result by

- * @param[out]      *pDst points to the output vector

- * @param[in]       blockSize number of samples in the vector

- * @return none.

- *

- * <b>Scaling and Overflow Behavior:</b>

- * \par

- * The input data <code>*pSrc</code> and <code>scaleFract</code> are in 1.7 format.

- * These are multiplied to yield a 2.14 intermediate result and this is shifted with saturation to 1.7 format.
